**[DEV](https://daily.dev/sources/devto)** · [@nickytonline](https://daily.dev/nickytonline) · 10 min read · 110 upvotes · 12 comments

## Summary

GitHub Copilot now supports custom extensions that integrate directly with Copilot. This guide walks you through setting up your project with Hono.js, creating and verifying request endpoints, and deploying your extension. The newly introduced Copilot SDK simplifies request verification, response formatting, and API interactions. Once developed, the extension can be tested in various environments like GitHub.com, VS Code, and Visual Studio.
